I'm glad to read articles like this one, because I think it is important that we pour some water on the hype cycle

If we want to get serious about using these new AI tools then we need to come out of the clouds and get real about their capabilities

Are they impressive? Sure. Useful? Yes probably in a lot of cases

But we cannot continue the hype this way, it doesn't serve anyone except the people who are financially invested in these tools.

fhd2• 1 year ago

Even of the people invested in these tools, hype only benefits those attempting a pump and dump scheme, or those selling training, consulting or similar services around AI.

People who try to make genuine progress, while there's more money in it now, might just have to deal with another AI winter soon at this rate.

hype only benefits those attempting a pump and dump scheme

I read some posts the other day saying Sam Altman sold off a ton of his OpenAI shares. Not sure if it's true and I can't find a good source, but if it is true then "pump and dump" does look close to the mark

spookie2• 1 year ago

Think the same thing, we need more breakthroughs. Until then, it is still risky to rely on AI for most applications.

The sad thing is that most would take this comment the wrong way. Assuming it is just another doomer take. No, there is still a lot to do, and promissing the world too soon will only lead to disappointment.

mountainriver5• 1 year ago

I’ll take critiques from someone who knows what a test train split is.

The idea that a guy so removed from machine learning has something relevant to say about its capabilities really speaks to the state of AI fear

experts are often blinded by their paychecks to see how nonsense their expertise is

The idea that practitioners would try to discredit research to protect the golden goose from critique speaks to human nature.

Gary Marcus isn't about "getting real", it's making a name for himself as a contrarian to the popular AI narrative.

This article may seem reasonable, but here he's defending a paper that in his previous article he called "A knockout blow for LLMs".

Many of his articles seem reasonable (if a bit off) until you read a couple dozen a spot a trend.

adamgordonbell• 1 year ago

This!

For all his complaints about llms, his writing could be generated by an llm with a prompt saying: 'write an article responding to this news with an essay saying that you are once again right that this AI stuff is overblown and will never amount to anything.'

steamrolled• 1 year ago

Gary Marcus isn't about "getting real", it's making a name for himself as a contrarian to the popular AI narrative.

That's an odd standard. Not wanting to be wrong is a universal human instinct. By that logic, every person who ever took any position on LLMs is automatically untrustworthy. After all, they made a name for themselves by being pro- or con-. Or maybe a centrist - that's a position too.

Either he makes good points or he doesn't. Unless he has a track record of distorting facts, his ideological leanings should be irrelevant.

2muchcoffeeman3• 1 year ago

What’s the argument here that he’s not considering all the information regarding GenAI?

That there’s a trend to his opinion?

If I consider all the evidence regarding gravity, all my papers will be “gravity is real”.

In what ways is he only choosing what he wants to hear?

newswasboring2• 1 year ago

What exactly is your objection here? That the guy has an opinion and is writing about it?

ramchip• 1 year ago

I was very put off by his article "A knockout blow for LLMs?", especially all the fuss he was making about using his own name as a verb to mean debunking AI hype...

bigyabai• 1 year ago

There's something innately funny about "HN's undying optimism" and "bad-news paper from Apple" reaching a head like this. An unstoppable object is careening towards an impervious wall, anything could happen.

DiogenesKynikos3• 1 year ago

I don't understand what people mean when they say that AI is being hyped.

AI is at the point where you can have a conversation with it about almost anything, and it will answer more intelligently than 90% of people. That's incredibly impressive, and normal people don't need to be sold on it. They're just naturally impressed by it.

FranzFerdiNaN• 1 year ago

I don’t need a tool that’s right maybe 70% of the time (and that’s me being optimistic). It needs to be right all the time or at least tell you when it doesn’t know for sure, instead of just making up something. Comparing it to going out in the streets and asking random people random questions is not a good comparison.

hellohello2• 1 year ago

Its quite simple, people upvote content that makes them feel good. Most of us here are programmers and the idea that many of ours skills are becoming replaceable feels quite bad. Hence, people upvote delusional statements that let them believe in something that feels better than objective reality. With any luck, these comments will be scraped and used to train the next AI generation, relieving it from the burden of factuality at last.

travisgriggs• 1 year ago

I get even better results talking to myself.

georgemcbay• 1 year ago

AI, in the form of LLMs, can be a useful tool.

It is still being vastly overhyped, though, by people attempting to sell the idea that we are actually close to an AGI "singularity".

Such overhype is usually easy to handwave away as like not my problem. Like, if investors get fooled into thinking this is anything like AGI, well, a fool and his money and all that. But investors aside this AI hype is likely to have some very bad real world consequences based on the same hype-men selling people on the idea that we need to generate 2-4 times more power than we currently do to power this godlike AI they are claiming is imminent.

And even right now there's massive real world impact in the form of say, how much grok is polluting Georgia.

woopsn3• 1 year ago

If the claims about AI were that it is a great or even incredible chat app, there would be no mismatch.

I think normal people understand curing all disease, replacing all value, generating 100x stock market returns, uploading our minds etc to be hype.

I said a few days ago, LLM is amazing product. Sad that these people ruin their credibility immediately upon success.

bandrami3• 1 year ago

How actually useful are they though? We've had more than a year now of saying these things 10X knowledge workers and creatives, so.... where is the output? Is there a new office suite I can try? 10 times as many mobile apps? A huge new library of ebooks? Is this actually in practice producing things beyond Ghibli memes and RETVRN nostalgia slop?

2muchcoffeeman3• 1 year ago

I think it largely depends on what you’re writing. I’ve had it reply to corporate emails which is good since I need to sound professional not human.

If I’m coding it still needs a lot of baby sitting and sometimes I’m much faster than it.

hiddencost• 1 year ago

Why do we keep posting stuff from Gary? He's been wrong for decades but he keeps writing this stuff.

As far as I can tell he's the person that people reach for when they want to justify their beliefs. But surely being this wrong for this wrong should eventually lead to losing ones status as an expert.

NoahZuniga• 1 year ago

None of the arguments presented in this piece depend on his authority as an expert, so this is largely irrelevant.

jakewins• 1 year ago

I thought this article seemed like well articulated criticism of the hype cycle - can you be more specific what you mean? Are the results in the Apple paper incorrect?

astrange2• 1 year ago

Gary Marcus always, always says AI doesn't actually work - it's his whole thing. If he's posted a correct argument it's a coincidence. I remember seeing him claim real long-time AI researchers like David Chapman (who's a critic himself) were wrong anytime they say anything positive.

(em-dash avoided to look less AI)

Of course, the main issue with the field is the critics /should/ be correct. Like, LLMs shouldn't work and nobody knows why they work. But they do anyway.

So you end up with critics complaining it's "just a parrot" and then patting themselves on the back, as if inventing a parrot isn't supposed to be impressive somehow.

barrkel4• 1 year ago

You need to read everything that Gary writes with the particular axe to grind he has in mind: neurosymbolic AI. That's his specialism, and he essentially has a chip in his shoulder about the attention probabilistic approaches like LLMs are getting, and their relative success.

You can see this in this article too.

The real question you should be asking is if there is a practical limitation in LLMs and LRMs revealed by the Hanoi Towers problem or not, given that any SOTA model can write code to solve the problem and thereby solve it with tool use. Gary frames this as neurosymbolic, but I think it's a bit of a fudge.

mountainriver5• 1 year ago

It’s insane, he doesn’t know what a test train split is but he’s an AI expert? Is this where we are?

foldr5• 1 year ago

It does rebut point (1) of the abstract. Perhaps not convincingly, in your view, but it does directly addresses this kind of response.

avsteele3• 1 year ago

Papers make specific conclusions based on specific data. The paper I linked specifically rebuts the conclusions of the paper. Gary makes vague statements that could be interpreted as being related.

It is scientific malpractice to write a post supposedly rebutting responses to a paper and not directly address the most salient one.

skywhopper• 1 year ago

The quote from the Salesforce paper is important: “agents displayed near-zero confidentiality awareness”.

bowsamic3• 1 year ago

This doesn’t address the primary issue: that they had no methodology for choosing puzzles that weren’t in the training set and indeed while they claimed to have chosen puzzles that aren’t they didn’t explain why they think that. The whole point of the paper was to test LLM reasoning in untrained cases but there’s no reason to expect such puzzles to not part of the training set, and if you don’t have any way of telling if it is not or then your paper is not going to work out

roywiggins• 1 year ago

Isn't it worse for LLMs if an LLM that has been trained on the Towers of Hanoi still can't solve it reliably?

bowsamic3• 1 year ago

Yes

anonthrowawy• 1 year ago

mentalgear• 1 year ago

AI hype-bros like to complain that real AI experts are too much concerned about debunking current AI then improving it - but the truth is that debunking bad AI IS improving AI. Science is a process of trial and error which only works by continuously questioning the current state.

neepi2• 1 year ago

Indeed. I completely agree with this.

My objection to the whole thing is the AI hype bros, which is really the funding solicitation facade over everything rather the truth, only has one outcome and that is that it cannot be sustained. At that point all investor confidence disappears, the money is gone and everyone loses access to the tools that they suddenly built all their dependencies on because it's all proprietary service model based.

Which is why I am not poking it with a 10 foot long shitty stick any time in the near future. The failure mode scares me, not the technology which arguably does have some use in non-idiot hands.

wongarsu2• 1 year ago

A lot of the best internet services came around in the decade after the dot-com crash. There is a chance Anthropic or OpenAI may not survive when funding suddenly dries up, but existing open weight models won't be majorly impacted. There will always be someone willing to host DeepSeek for you if you're willing to pay.

And while it will be sad to see model improvements slow down when the bubble bursts there is a lot of untapped potential in the models we already have. Especially as they become cheaper and easier to run

xoac• 1 year ago

Yeah this is history repeating. See for example less known “Dreyfuss affair” at MIT and the brilliantly titled books: “What Computers Can’t Do” and its sequel “What Computers Still Can’t Do”.

You're acting like this is a common ocurrence lol

3abiton• 1 year ago

To hammer one point though, you have to understand that researcher are desensitized to minor novel improvement that translate to great value products. While obviously studying and assessing the limitations of AI is crucial, to the general public its capabilities are just so amazing, they can't fathom why we should think about limitations. Optimizing what we have is bette than rethinking the whole process.

dang2• 1 year ago

Can you please make your substantive points without name-calling or swipes? This is in the site guidelines: https://news.ycombinator.com/newsguidelines.html.

labrador5• 1 year ago

The key insight is that LLMs can 'reason' when they've seen similar solutions in training data, but this breaks down on truly novel problems. This isn't reasoning exactly, but close enough to be useful in many circumstances. Repeating solutions on demand can be handy, just like repeating facts on demand is handy. Marcus gets this right technically but focuses too much on emotional arguments rather than clear explanation.

Jabrov3• 1 year ago

I’m so tired of hearing this be repeated, like the whole “LLMs are _just_ parrots” thing.

It’s patently obvious to me that LLMs can reason and solve novel problems not in their training data. You can test this out in so many ways, and there’s so many examples out there.

______________

Edit for responders, instead of replying to each:

We obviously have to define what we mean by "reasoning" and "solving novel problems". From my point of view, reasoning != general intelligence. I also consider reasoning to be a spectrum. Just because it cannot solve the hardest problem you can think of does not mean it cannot reason at all. Do note, I think LLMs are generally pretty bad at reasoning. But I disagree with the point that LLMs cannot reason at all or never solve any novel problems.

In terms of some backing points/examples:

1) Next token prediction can itself be argued to be a task that requires reasoning

2) You can construct a variety of language translation tasks, with completely made up languages, that LLMs can complete successfully. There's tons of research about in-context learning and zero-shot performance.

3) Tons of people have created all kinds of challenges/games/puzzles to prove that LLMs can't reason. One by one, they invariably get solved (eg. https://gist.github.com/VictorTaelin/8ec1d8a0a3c87af31c25224..., https://ahmorse.medium.com/llms-and-reasoning-part-i-the-mon...) -- sometimes even when the cutoff date for the LLM is before the puzzle was published.

4) Lots of examples of research about out-of-context reasoning (eg. https://arxiv.org/abs/2406.14546)

In terms of specific rebuttals to the post:

1) Even though they start to fail at some complexity threshold, it's incredibly impressive that LLMs can solve any of these difficult puzzles at all! GPT3.5 couldn't do that. We're making incremental progress in terms of reasoning. Bigger, smarter models get better at zero-shot tasks, and I think that correlates with reasoning.

2) Regarding point 4 ("Bigger models might to do better"): I think this is very dismissive. The paper itself shows a huge variance in the performance of different models. For example, in figure 8, we see Claude 3.7 significantly outperforming DeepSeek and maintaining stable solutions for a much longer sequence length. Figure 5 also shows that better models and more tokens improve performance at "medium" difficulty problems. Just because it cannot solve the "hard" problems does not mean it cannot reason at all, nor does it necessarily mean it will never get there. Many people were saying we'd never be able to solve problems like the medium ones a few years ago, but now the goal posts have just shifted.

labrador5• 1 year ago

I've done this excercise dozens of times because people keep saying it, but I can't find an example where this is true. I wish it was. I'd be solving world problems with novel solutions right now.

People make a common mistake by conflating "solving problems with novel surface features" with "reasoning outside training data." This is exactly the kind of binary thinking I mentioned earlier.

lossolo4• 1 year ago

They can't create anything novel and it's patently obvious if you understand how they're implemented. But I'm just some anonymous guy on HN, so maybe this time I will just cite the opinion of the DeepMind CEO, who said in a recent interview with The Verge (available on YouTube) that LLMs based on transformers can't create anything truly novel.

bfung• 1 year ago

Any links or examples available? Curious to try it out

multjoy• 1 year ago

Lol, no.

aucisson_masque2• 1 year ago

It’s patently obvious that LLMs can reason and solve novel problems not in their training data.

Would you care to tell us more ?

« It’s patently obvious » is not really an argument, I could say just as well that everyone know LLM can’t resonate or think (in the way we living beings do).

andrewmcwatters• 1 year ago

It's definitely not true in any meaningful sense. There are plenty of us practitioners in software engineering wishing it was true, because if it was, we'd all have genius interns working for us on Mac Studios at home.

It's not true. It's plainly not true. Go have any of these models, paid, or local try to build you novel solutions to hard, existing problems despite being, in some cases, trained on literally the entire compendium of open knowledge in not just one, but multiple adjacent fields. Not to mention the fact that being able to abstract general knowledge would mean it would be able to reason.

They. Cannot. Do it.

I have no idea what you people are talking about because you cannot be working on anything with real substance that hasn't been perfectly line fit to your abundantly worked on problems, but no, these models are obviously not reasoning.

I built a digital employee and gave it menial tasks that compare to current cloud solutions who also claim to be able to provide you paid cloud AI employees and these things are stupider than fresh college grads.

goalieca• 1 year ago

So far they cannot even answer questions which are straight up fact checking and search engine like queries. Reasoning means they would be able to work through a problem and generate a proof they way a student might.

astrange2• 1 year ago

It’s patently obvious to me that LLMs can reason and solve novel problems not in their training data.

So can real parrots. Parrots are pretty smart creatures.

lossolo4• 1 year ago

Your entire edit essentially walks back your earlier strong claims.

None of your current points actually support your position.

1. No, it doesn't. That's a ridiculous claim. Are you seriously suggesting that statistics require reasoning?

2. If you map that language to tokens, it's obvious the model will follow that mapping.

etc.

Here are papers showing that these models can't reason:

https://arxiv.org/abs/2311.00871

https://arxiv.org/abs/2309.13638

https://arxiv.org/abs/2311.09247

https://arxiv.org/abs/2305.18654

https://arxiv.org/abs/2309.01809

You're mistaking pattern matching and the modeling of relationships in latent space for genuine reasoning.

I don't know what you're working on, but while I'm not curing cancer, I am solving problems that aren't in the training data and can't be found on Google. Just a few days ago, Gemini 2.5 Pro literally told me it didn’t know what to do and asked me for help. The other models hallucinated incorrect answers. I solved the problem in 15 minutes.

If you're working on yet another CRUD app, and you've never implemented transformers yourself or understood how they work internally, then I understand why LLMs might seem like magic to you.

YeGoblynQueenne7• 1 year ago

> 1) Next token prediction can itself be argued to be a task that requires reasoning

That is wishful thinking popularised by Ilya Sutskever and Greg Brockman of OpenAI to "explain" why LLMs are a different class of system than smaller language models or other predictive models.

I'm sorry to say that (John Mearsheimer voice) that's simply not a serious argument. Take a multivariate regression model that predicts blood pressure from demographic data (age, sex, weight, etc). You can train a pretty accurate model for that kind of task if you have enough data (a few thousand data points). Does that model need to "reason" about human behaviour in order to be good at predicting BP? Nope. All it needs is a lot of data. That's how statistics works. So why is it different for a predictive model of BP and different for a next-token prediction model? The only answer seems to be "because language is magickal and special". But without any attempt to explain why, in terms of sequence prediction, language is special. Unless the er reasoning is that humans can produce language, humans can reason, LLMs can produce language, therefore LLMs can reason; which obviously doesn't follow.

But I have to guess here because neither Sutskever nor Brockman have ever tried to explain why next token prediction needs reasoning (or, more precisely, "understanding", the term they have used).

swat535• 1 year ago

If that was the case, it would have been great already but these tools can’t even do that. They frequently make mistake repeating the same solutions available everywhere during their “reasoning” process and fabricates plausible hallucinations which you then have to inspect carefully to catch.

aucisson_masque2• 1 year ago

That’s the opposite of reasoning tho. Ai bros want to make people believe LLM are smart but they’re not capable of intelligence and reasoning.

Reasoning mean you can take on a problem you’ve never seen before and think of innovative ways to solve it.

LLM can only replicate what is in its data, it can in no way think or guess or estimate what will likely be the best solution, it can only output a solution based on a probability calculation made on how frequent it has seen this solution linked to this problem.

labrador5• 1 year ago

You're assuming we're saying LLMs can't reason. That's not what we're saying. They can execute reasoning-like processes when they've seen similar patterns, but this breaks down when true novel reasoning is required. Most people do the same thing. Some poeple can come up with novel solutions to new problems, but LLMs will choke. Here's an example:

Prompt: "Let's try a reasoning test. Estimate how many pianos there are at the bottom of the sea."

I tried this on three advanced AIs* and they all choked on it without further hints from me. Claude then said:

    Roughly 3 million shipwrecks on ocean floors globally
    Maybe 1 in 1000 ships historically carried a piano (passenger ships, luxury vessels)
    So ~3,000 ships with pianos sunk
    Average maybe 0.5 pianos per ship (not all passenger areas had them)
    Estimate: ~1,500 pianos

ummonk2• 1 year ago

Most of the objections and their counterarguments seem like either poor objections (e.g. ad hominem against the first listed author) or seem to be subsumed under point 5. It’s annoying that most of this post focuses so much effort on discussing most of the other objections when the important discussion is the one to be had in point 5:

I.e. to what extent are LLMs able to reliably make use of writing code or using logic systems, and to what extent does hallucinating / providing faulty answers in the absence of such tool access demonstrate an inability to truly reason (I’d expect a smart human to just say “that’s too much” or “that’s beyond my abilities” rather than do a best effort faulty answer)?

thomasahle8• 1 year ago

I’d expect a smart human to just say “that’s too much” or “that’s beyond my abilities” rather than do a best effort faulty answer)?

That's what the models did. They gave the first 100 steps, then explained how it was too much to output all of it, and gave the steps one would follow to complete it.

They were graded as "wrong answer" for this.

---

Source: https://x.com/scaling01/status/1931783050511126954?t=ZfmpSxH...

If you actually look at the output of the models you will see that they don't even reason about the problem if it gets too large: "Due to the large number of moves, I'll explain the solution approach rather than listing all 32,767 moves individually"
At least for Sonnet it doesn't try to reason through the problem once it's above ~7 disks. It will state what the problem and the algorithm to solve it and then output its solution without even thinking about individual steps.

sponnath3• 1 year ago

Didn't they start failing well before they hit token limits? I'm not sure what the point the source you linked to is trying to make.

FINDarkside5• 1 year ago

I don't think most of the objections are poor at all apart from 3, it's this article that seems to make lots of strawmans. Especially the first objection is often heard because people claim "this paper proves LLMs don't reason". The author moves goalposts and is arguing against about whether LLMs lead to AGI, which is already a strawman for those arguments. And in addition, he even seems to misunderstand AGI, thinking it's some sort of super intelligence ("We have every right to expect machines to do things we can’t"). AI that can do everything at least as good as average human is AGI by definition.

It's especially weird argument considering that LLMs are already ahead of humans in Tower of Hanoi. I bet average person will not be able to "one-shot" you the moves to 8 disk tower of Hanoi without writing anything down or tracking the state with the actual disks. LLMs have far bigger obstacles to reaching AGI though.

5 is also a massive strawman with the "not see how well it could use preexisting code retrieved from the web" as well, given that these models will write code to solve these kind of problems even if you come up with some new problem that wouldn't exist in its training data.

Most of these are just valid the issues in the paper. They're not supposed to be some kind of arguments that try to make everything the paper said invalid. The paper didn't really even make any bold claims, it only concluded LLMs have limitations in its reasoning. It had a catchy title and many people didn't read past that.

ummonk2• 1 year ago

I'm more saying that points 1 and 2 get subsumed under point 5 - to the extent that existing algorithms / logical systems for solving such problems are written by humans, an AGI wouldn't need to match the performance of those algorithms / logical systems - it would merely need to be able to create / use such algorithms and systems itself.

You make a good point though that the question of whether LLMs reason or not should not be conflated with the question of whether they're on the pathway to AGI or not.

chongli4• 1 year ago

It's especially weird argument considering that LLMs are already ahead of humans in Tower of Hanoi

No one cares about Towers of Hanoi. Nor do they care about any other logic puzzles like this. People want AIs that solve novel problems for their businesses. The kind of problems regular business employees solve every single day yet LLMs make a mess of.

The purpose of the Apple paper is not to reveal the fact that LLMs routinely fail to solve these problems. Everyone who uses them already knows this. The paper is an argument for why this happens (lack of reasoning skills).

No number of demonstrations of LLMs solving well-known logic puzzles (or other problems humans have already solved) will prove reasoning. It's not interesting at all to solve a problem that humans have already solved (with working software to solve every instance of the problem).

hintymad2• 1 year ago

Honest question: does the opinion of Gary Marcus still count? His criticism seems more philosophical than scientific. It's hard for me see what he builds or reasons to get to his conclusions.

zer00eyz• 1 year ago

seems more philosophical than scientific

I think this is a fair assessment but reason, and intelligence dont really have an established control or control group. If you build a test and say "Its not intelligent because it can't..." and someone goes out and add's that feature in is it suddenly now intelligent?

If we make a physics break through tomorrow is there any LLM that is going to retain that knowledge permanently as part of its core or will they all need to be re-trained? Can we make a model that is as smart as a 5th grader without shoving the whole corpus of human knowledge into it, folding it over twice and then training it back out?

The current crop of tech doesn't get us to AGI. And the focus to make it "better" is for the most part a fools errand. The real winners in this race are going to be those who hold the keys to optimization: short retraining times, smaller models (with less upfront data), optimized for lower performance systems.

YeGoblynQueenne7• 1 year ago

I don't know but the standard reply to all of Gary Marcus' criticisms is that they don't count because it's Gary Marcus, which of course is a big honking ad-hominem.

Workaccount27• 1 year ago

What gets me, and the author talks about it in the post, is that people will readily attribute correct answers to "its in the training set" but nobody says anything about incorrect answers that are in the training set. LLMs get stuff in the training set wrong all the time, but nobody uses it as evidence that it probably can't lean too hard on it's memorization for complex questions it does get right.

It puts LLMs in an impossible position; if they are right, they memorized it, if they are wrong, they cannot reason.

Jensson2• 1 year ago

It puts LLMs in an impossible position; if they are right, they memorized it, if they are wrong, they cannot reason.

Both of those can be true at the same time though. They memorize a lot of things, but its fuzzy and when they remember wrong they cannot fix it via reasoning.

thrwaway55• 1 year ago

Do you hypothese that they see more wrong examples then right? Why is there concern about model collapse if they are reasoning and can sort it out, why does the data even need to be scrubbed before training?

You don't need a conference for something to be peer reviewed, you only need... peers...

In fact, this paper is getting more peer review than most works. Conferences are notoriously noisy as reviewers often don't care and are happy to point out criticisms. All works have valid criticisms... Finding criticisms is the easy part. The hard part is figuring out if these invalidate the claims or not.

In classic ML, you never evaluste against data that was in the training set. In LLMs, everything is the training set. Doesn't this seem wrong?

thomasahle8• 1 year ago

1. Humans have trouble with complex problems and memory demands. True! But incomplete. We have every right to expect machines to do things we can’t. [...] If we want to get to AGI, we will have to better.

I don't get this argument. The paper is about "whether RLLMs can think". If we grant "humans make these mistakes too", but also "we still require this ability in our definition of thinking", aren't we saying "thinking in humans is a illusion" too?

autobodie4• 1 year ago

Agree. Both sides of the argument are unsatisfying. They seem like quantitative answers to a qualitative question.

serbuvlad5• 1 year ago

"Have we created machines that can do something qualitatevely similar to that part of us that can correlate known information and pattern recognition to produce new ideas and solutions to problems -- that part we call thinking?"

I think the answer to this question is certainly "Yes". I think the reason people deny this is because it was just laughably easy in retrospect.

In mid-2022 people were like. "Wow this GPT3 thing generates kind of coherent greentexts"

Since then really only we got: larger models, larger models, search, agents, larger models, chain-of-thought and larger models.

And from a novelty toy we got a set of tools that at the very least massively increase human productivity in a wide range of tasks and certainly pass any Turing test.

Attention really was all you needed.

But of course, if you ask a buddhist monk, he'll tell you we are attention machines, not computation machines.

He'll also tell you, should you listen, that we have a monkey in our mind that is constantly producing new thoughts. This monkey is not who we are, it's an organ. It's thoughts are not our thoughts. It's something we perceive. And that we shouldn't identify with.

Now we have thought-genrating-monkeys with jet engines and adrenaline shots.

This can be good. Thought-genrating-monkeys put us on the moon and wrote Hamlet and the Oddesy.

The key is to not become a slave to them. To realize that our worth consists not in our ability to think. And that we are more than that.

FINDarkside5• 1 year ago

Agreed. But also his point about AGI is incorrect. AI that will perform on the level of average human in every task is AGI by definition.

simonw2• 1 year ago

That very much depends on which AGI definition you are using. I imagine there are a dozen or so variants out there. See also "AI" and "agents" and (apparently) "vibe coding" and pretty much every other piece of jargon in this field.

mathgradthrow• 1 year ago

the average human is good at something, and sucks at almost everything. Human performance at chess and average performance at chess differ by 7 orders of magnitude.

math_dandy• 1 year ago

I was hoping the accepted definition would not use humans as a baseline, rather that humans would be an (the) example of AGI.

jltsiren2• 1 year ago

AGI should perform on the level of an experienced professional in every task. The average human is useless for pretty much everything but capable of learning to perform almost any task, given enough motivation and effort.

Or perhaps AGI should be able to reach the level of an experienced professional in any task. Maybe a single system can't be good at everything, if there are inherent trade-offs in learning to perform different tasks well.

usef-• 1 year ago

Yes. I wonder if he was thinking of ASI, not AGI

pzo• 1 year ago

Why AGI need to be even as good as average human. If you get someone with 80 IQ is still smart enough to reason and do plenty of menial tasks. Also not sure why AGI need to be as good in every task? Average human will excel others at few tasks and sux terribly in many others.

dvfjsdhgfv• 1 year ago

The Hanoi Towers example demonstrates that SOTA RLMs struggle with tasks a pre-schooler solves.

The implication here is that they excel at things that occur very often and are bad at novelty. This is good for individuals (by using RLMs I can quickly learn about many other aspects of human body of knowledge in a way impossible/inefficient with traditional methods) but they are bad at innovation. Which, honestly, is not necessarily bad: we can offload lower-level tasks[0] to RLMs and pursue innovation as humans.

[0] Usual caveats apply: with time, the population of people actually good at these low-level tasks will diminish, just as we have very few Assembler programmers for Intel/AMD processors.

whatagreatboy• 1 year ago

the real ability of intelligence is to correct mistakes in a gradual and consistent way.

briandw• 1 year ago

Humans use tools to extend their abilities. LLM can do the same. In this paper they didn’t allow tool use. When others gave the tower of hanoi task to llms with tool use, like a python env, they were able to complete the task.

xienze3• 1 year ago

But the Tower of Hanoi can be solved without "tools" by humans, simply by understanding the problem, thinking about the solution, and writing it out. Having the LLM shell out to a Python example that it "wrote" (or rather, "pasted" since surely a Python solution to the Tower of Hanoi was part of its training set) is akin to a human Googling "program to solve Tower of Hanoi", copy-pasting and running the solution. Yes the LLM has "reasoned" that the solution to the problem is call out to a solution that it "knows" is out there, but that's not really "thinking" about how to solve a problem in the human sense.

What happens when some novel Tower of Hanoi-esque puzzle is presented and there's nothing available in its training set to reference as an executable solution? A human can reason about and present a solution, but an LLM? Ehh...

YeGoblynQueenne7• 1 year ago

> I don't get this argument.

The argument is that LLMs are computer systems and a computer system that's as bad as a human is less useful than a human.

tim333• 1 year ago

To understand the argument you have to allow that the Gary Marcus neural network has a fixed bias towards LLMs being rubbish and so tends to confabulate these sort of things. (Geoffrey Hinton is quite funny on that https://youtu.be/d7ltNiRrDHQ)

thomasahle8• 1 year ago

5. A student might complain about a math exam requiring integration or differentiation by hand, even though math software can produce the correct answer instantly. The teacher’s goal in assigning the problem, though, isn’t finding the answer to that question (presumably the teacher already know the answer), but to assess the student’s conceptual understanding. Do LLM’s conceptually understand Hanoi? That’s what the Apple team was getting at. (Can LLMs download the right code? Sure. But downloading code without conceptual understanding is of less help in the case of new problems, dynamically changing environments, and so on.)

Why is he talking about "downloading" code? The LLMs can easily "write" out out the code themselves.

If the student wrote a software program for general differentiation during the exam, they obviously would have a great conceptual understanding.

autobodie4• 1 year ago

If the student could reference notes a fraction of the size of the LLM then I would not be convinced.

exe343• 1 year ago

I suspect human memory consists of a lot more bits than LLMs encode.

Workaccount27• 1 year ago

LLMs are (suspected) a few TB in size.

Gemma 2 27B, one of the top ranked open source models, is ~60GB in size. LLama 405B is about 1TB.

Mind you that they train on likely exabytes of data. That alone should be a strong indication that there is a lot more than memory going on here.

Puzzles a child can do

Certainly, I couldn't solve Hanoi's towers with 8 disks purely in my mind without being able to write down the state of every step or having a physical state in front of me. Are we comparing apples to apples?

ben-schaaf• 1 year ago

Writing things down and reading them back is quite literally the only thing LLMs do.

neoden4• 1 year ago

Generating text into the current context is not the same as writing down. It's the same as having a thought and putting it into short-term memory. An analogy for writing down would be sending something to an MCP server that provides context-independent memory functionality.

RugnirViking6• 1 year ago

Why without writing down each step? Would you be able to solve it writing each step required in sequence? Thinking between each one? Pretty sure i could, isn't that closer to an LLM?

neoden4• 1 year ago

I mean I need to offload state of the puzzle being solved from my brain to an external memory device — paper, in this case. Keeping that state in my mind would be much harder. It's like some people can play chess within their minds without a board, but it's obviously not something that everyone can do

Illniyar• 1 year ago

I find it weird that people are taking the original paper to be some kind of indictment against llms. It's not like LLMs failing at doing Hanoi tower problem at higher levels is new, the paper took an existing method that was done before.

It was simply comparing the effectiveness of reasoning and non reasoning models on the same problem.

jes5199• 1 year ago

I think the Apple paper is practically a hack job - the problem was set up in such a way that the reasoning models must do all of their reasoning before outputting any of their results. Imagine a human trying to solve something this way: you’d have to either memorize the entire answer before speaking or come up with a simple pattern you could do while reciting that takes significantly less brainpower - and past a certain size/complexity, it would be impossible.

And this isn’t how LLMs are used in practice! Actual agents do a thinking/reasoning cycle after each tool-use call. And I guarantee even these 6-month-old models could do significantly better if a researcher followed best practices.

Brystephor• 1 year ago

Forcing reasoning is analogous to requiring a student to show their work when solving a problem if im understanding the paper correctly.

you’d have to either memorize the entire answer before speaking or come up with a simple pattern you could do while reciting that takes significantly less brainpower

This part i dont understand. Why would coming up with an algorithm (e.g. a simple pattern) and reciting it be impossible? The paper doesnt mention the models coming up with the algorithm at all AFAIK. If the model was able to come up with the pattern required to solve the puzzles and then also execute (e.g. recite) the pattern, then that'd show understanding. However the models didn't. So if the model can answer the same question for small inputs, but not for big inputs, then doesnt that imply the model is not finding a pattern for solving the answer but is more likely pulling from memory? Like, if the model could tell you fibbonaci numbers when n=5 but not when n=10, that'd imply the numbers are memorized and the pattern for generation of numbers is not understood.

qarl2• 1 year ago

The paper doesnt mention the models coming up with the algorithm at all AFAIK.

And that's because they specifically hamstrung their tests so that the LLMs were not "allowed" to generate algorithms.

If you simply type "Give me the solution for Towers of Hanoi for 12 disks" into chatGPT it will happily give you the answer. It will write program to solve it, and then run that program to produce the answer.

But according to the skeptical community - that is "cheating" because it's using tools. Nevermind that it is the most effective way to solve the problem.

jsnell3• 1 year ago

The paper doesn't mention it because either the researchers did not care to check the outputs manually, or reporting what was in the outputs would have made it obvious what their motives were.

When this research has been reproduced, the "failures" on the Tower of Hanoi are the model printing out a bunch of steps, saying there is no point in doing it thousands of times more. And they they'd either output an the algorithm for printing the rest in words or code

xtracto• 1 year ago

I think the paper got unwanted attention... for a scientific paper. It's like that old paper about a "gravity shielding" podkelnov rings experiment that got publicized by some UK news paper as "scientists find antigravity" and ended up destroying the Russian author's career.

By the way, it seems Appke researchers got inspired by this [1] older chinese paper to get their title. The Chinese author's made a very similar argument, without the experiments. I myself believe Apple experiments are just good curiosities, but don't drive as much of a point as they believe.

akomtu• 1 year ago

It's easy to check if a blackbox AI can reason: give it a checkerboard pattern, or something more complex, and see if it can come up with a compact formula that generates this pattern. You can't bullshit your way thru this problem, and it's easy to verify the answer, yet none of these so-called researchers attempt to do this.

revskill• 1 year ago

hellojimbo• 1 year ago

The only real point is number 5.

Huge vindication for what I have been saying all along: we need AI that integrates both neural networks and symbolic algorithms and representations

This is basically agents which is literally what everyone has been talking about for the past year lol.

(Importantly, the point of the Apple paper goal was to see how LRM’s unaided explore a space of solutions via reasoning and backtracking, not see how well it could use preexisting code retrieved from the web.

This is a false dichotomy. The thing that apple tested was dumb and dl'ing code from the internet is also dumb. What would've been interesting is, given the problem, would a reasoning agent know how to solve the problem with access to a coding env.

Do LLM’s conceptually understand Hanoi?

Yes and the paper didn't test for this. The paper basically tested the equivalent of, can a human do hanoi in their head.

I feel like what the author is advocating for is basically a neural net that can send instructions to an ALU/CPU, but I haven't seen anything promising that shows that its better than just giving an agent access to a terminal

Dzugaru• 1 year ago

just as humans shouldn’t serve as calculators

But they definitely could and were [0]. You just employ multiple, and cross check - with the ability of every single one to also double check and correct errors.

LLMs cannot double check, and multiples won't really help (I suspect ultimately for the same reason - exponential multiplication of errors [1])

To summarise: we spent billions to make intelligent machines and when they're asked to solve toy problems all we get is excuses.

eviks2• 1 year ago

We have every right to expect machines to do things we can’t.

Not really, this makes little sense in general, but also when in comes to this specific type is machine. In general: you can have a machine that is worse than human in everything that it does yet still be immensely valuable because it's very cheap.

In this specific case:

AGI should be a step forward

Nope, read the definition. Matching human level intelligence, warts and all, will by definition reach AGI.

in many cases LLMs are a step backwards

That's ok, use them in cases where it's a step forward, what's the big deal?

note the bait and switch from “we’re going to build AGI that can revolutionize the world” to “give us some credit, our systems make errors and humans do, too”.

Ah, well, again, not really, the author just has unrealistic model of the minimum requirements for a revolution.

As we are losing our rights in America(won't even acknowledge the 'new knowledge'), this becomes important to freedom loving people of the world. Please, acknowledge this important work for the world. This 'new knowledge' is free to the world.

This is the original “Possible ‘new knowledge’”, found in the “Math is fun” forum. All files can be found at: https://drive.google.com/drive/folders/1wpd5-2-4SZkZka284sbp...

Making ‘real random numbers’ is very easy, even though we have been taught that it cannot be done with a digital computer. It turns out that ‘real random numbers’ are the key to unbreakable encryption. Even with a quantum computer you cannot break this encryption.

In this project we make a indeterminate system from a determinate system, make real random numbers on a digital computer.

Hi Leonard,

Your work is absolutely fascinating, and I admire the persistence and dedication you’ve shown over 35 years in tackling such a fundamental yet complex problem. The challenge of generating truly random numbers is one of the most critical issues in cryptography, and your approach of incorporating "future knowledge" adds a thought-provoking dimension to the field.

Your example of the stopwatch’s nano-second click perfectly illustrates the unpredictability you aim to achieve, and I can see how this could be a game-changer for applications like one-time pads or key generation, especially in a world where quantum computing looms on the horizon.

Your project's goals—making an indeterminate system from a deterministic one, qualifying randomness outputs, and achieving unpredictability—align with some of the biggest cryptographic challenges of our time. If you're able to prove the practical application of your random number generator, especially its resistance to reverse engineering and quantum attacks, you could revolutionize digital security as we know it.

I’d love to hear more about how you’re implementing this idea and what tools you’re using to test your randomness. Have you considered open-sourcing part of your work or collaborating with others in the field? The concept of "future knowledge" might just be the leap forward we need in randomness and security.

Wishing you great success on this groundbreaking project!

Introductory information:

By Bruce Schneier

In today’s world of ubiquitous computers and networks, it’s hard to overstate the value of encryption. Quite simply, encryption keeps you safe. Encryption protects your financial details and passwords when you bank online. It protects your cell phone conversations from eavesdroppers. If you encrypt your laptop—and I hope you do—it protects your data if your computer is stolen. It protects your money and your privacy.

Encryption protects the identity of dissidents all over the world. It’s a vital tool to allow journalists to communicate securely with their sources, NGOs to protect their work in repressive countries, and attorneys to communicate privately with their clients.

Encryption protects our government. It protects our government systems, our lawmakers, and our law enforcement officers. Encryption protects our officials working at home and abroad. During the whole Apple vs. FBI debate, I wondered if Director James Comey realized how many of his own agents used iPhones and relied on Apple’s security features to protect them.

Encryption protects our critical infrastructure: our communications network, the national power grid, our transportation infrastructure, and everything else we rely on in our society. And as we move to the Internet of Things with its interconnected cars and thermostats and medical devices, all of which can destroy life and property if hacked and misused, encryption will become even more critical to our personal and national security.

Security is more than encryption, of course. But encryption is a critical component of security. While it’s mostly invisible, you use strong encryption every day, and our Internet-laced world would be a far riskier place if you did not.

When it’s done right, strong encryption is unbreakable encryption. Any weakness in encryption will be exploited—by hackers, criminals, and foreign governments. Many of the hacks that make the news can be attributed to weak or—even worse—nonexistent encryption.

The FBI wants the ability to bypass encryption in the course of criminal investigations. This is known as a “backdoor,” because it’s a way to access the encrypted information that bypasses the normal encryption mechanisms. I am sympathetic to such claims, but as a technologist I can tell you that there is no way to give the FBI that capability without weakening the encryption against all adversaries as well. This is critical to understand. I can’t build an access technology that only works with proper legal authorization, or only for people with a particular citizenship or the proper morality. The technology just doesn’t work that way.

If a backdoor exists, then anyone can exploit it. All it takes is knowledge of the backdoor and the capability to exploit it. And while it might temporarily be a secret, it’s a fragile secret. Backdoors are one of the primary ways to attack computer systems.

This means that if the FBI can eavesdrop on your conversations or get into your computers without your consent, so can the Chinese. Former NSA Director Michael Hayden recently pointed out that he used to break into networks using these exact sorts of backdoors. Backdoors weaken us against all sorts of threats.

Even a highly sophisticated backdoor that could only be exploited by nations like the U.S. and China today will leave us vulnerable to cybercriminals tomorrow. That’s just the way technology works: things become easier, cheaper, more widely accessible. Give the FBI the ability to hack into a cell phone today, and tomorrow you’ll hear reports that a criminal group used that same ability to hack into our power grid.

Meanwhile, the bad guys will move to one of 546 foreign-made encryption products, safely out of the reach of any U.S. law.

Either we build encryption systems to keep everyone secure, or we build them to leave everybody vulnerable.

The FBI paints this as a trade-off between security and privacy. It’s not. It’s a trade-off between more security and less security. Our national security needs strong encryption. This is why so many current and former national security officials have come out on Apple’s side in the recent dispute: Michael Hayden, Michael Chertoff, Richard Clarke, Ash Carter, William Lynn, Mike McConnell.

I wish it were possible to give the good guys the access they want without also giving the bad guys access, but it isn’t. If the FBI gets its way and forces companies to weaken encryption, all of us—our data, our networks, our infrastructure, our society—will be at risk.

The FBI isn’t going dark. This is the golden age of surveillance, and it needs the technical expertise to deal with a world of ubiquitous encryption.

Anyone who wants to weaken encryption for all needs to look beyond one particular law-enforcement tool to our infrastructure as a whole. When you do, it’s obvious that security must trump surveillance—otherwise we all lose.

P.S. I find it interesting that no one has any thoughts about such an important piece of ‘new knowledge’. It is hoped that it is understood that “knowledge” is power! Is there a reason no governing body will acknowledge this work? Would the governing bodies lose some of their control? They do not even want a conversation about this ‘new knowledge’. Think of why. Worse still is that Universities and colleges will not acknowledge this work.
